Easy walk by on coast path from or to Bolt Head. Bit of a path through scratchy veg. Pillar on its concrete base. Views becoming limited as the vegetation grows. Original cap, one view hole open. I think the OS may have spelt the name incorrectly - East Sewer = East Soar. You know what army types are like.

vgc, metal cap, shallow letters, BSM style FB. at fence corner just W of coast path. Fine view of Salcombe & Harbour from path a few m to N. Pity about the name ! Coincidentally visited S3400 later the same afternoon.
